  • Patent number: 6796151
    Abstract: A method and a device for dyeing a textile substrate in at least one supercritical fluid, are described, whereby the textile substrate is arranged in an autoclave, where at least one supercritical fluid loaded with a dyestuff flows over and/or through the textile substrate, and the at least one powdered dyestuff is brought in contact with the supercritical fluid, forming a stable solution and/or dispersion of the dyestuff in the supercritical fluid. The quantity of dyestuff required for dyeing is divided into a plurality of dyestuff partial quantities, and each partial quantity of dyestuff is separately brought in contact with the supercritical fluid until this partial quantity of dyestuff is dissolved or dispersed. Hereafter the next partial quantity of dyestuff is introduced into the supercritical fluid, and this process is repeated several times until the total quantity of dyestuff has been introduced into the supercritical fluid.

  • Patent number: 6609264
    Abstract: A drain pump of a washing machine is cyclically activated during a drain operation conducted as part of a spin cycle in a manner which reduces the run time of the pump. At least one dynamic operating parameter of the washing machine is sensed and used to control the operation of the drain pump. In accordance with a preferred embodiment of the invention, the rotational speed of the wash tub is sensed and, when a predetermined spin speed is maintained for a prescribed period of time, the drain operation is initiated. Water level, pump power and/or drive motor torque can also be utilized as pump cycling control parameters.

  • Patent number: 6594841
    Abstract: An unbalance detection and control system senses an out-of-balance condition developed during a plaster speed portion of spin cycle in a washing machine, particularly a horizontal axis washing machine, through fluctuations in command signals sent from a main controller to maintain a spinning basket or tub of the washing machine at plaster speed. Preferably, the controller sends a pulse width modulated (PWM) signal to a drive controller which, in turn, regulates a motor used to spin the tub. A feedback loop is employed to reflect an actual operational state achieved by the spinning tub, which may warrant a change in the command signal. Excessive fluctuations in the command signals indicate a need to redistribute the load of clothes in the tub.

  • Patent number: 6578591
    Abstract: The present invention relates to a dishwasher with enhanced drying performance without using a fan. Water contained in the dishwasher is circulated preferably by means of one of the pumps in the machine (circulation or discharge pump) and through a jet pump placed in the dishwasher in such a manner that the air intake opening is in communication with one of the wash tub surfaces. Water within the dishwasher accelerates due to the kinetic energy acquired during this circulation and its pressure drops locally to a value below the atmospheric pressure. Due to this reduced pressure, water vapour and air from the washtub is suctioned from the tub.
